Accelerated coplanar facet radio synthesis imaging
(2016)
Imaging in radio astronomy entails the Fourier inversion of the relation between the sampled spatial coherence of an electromagnetic field and the intensity of its emitting source. This inversion is normally computed by ...
Crowdsourcing a text corpus for a low resource language
(2016)
Low resourced languages, such as South Africa's isiXhosa, have a limited number of digitised texts, making it challenging to build language corpora and the information retrieval services, such as search and translation ...

(2016)
This dissertation investigates the challenges that Deaf adults encounter at the task of learning computer literacy skills. Deaf adults who communicate using South African Sign Language (SASL) come from poor socio-economic ...
Procedurally generated realistic virtual rural worlds
(2016)
Manually creating virtual rural worlds is often a difficult and lengthy task for artists, as plant species selection, plant distributions and water networks must be deduced such that they realistically reflect the environment ...
Deep Learning without Poor Local Minima
(2016-05-23)
In this paper, we prove a conjecture published in 1989 and also partially address an open problem announced at the Conference on Learning Theory (COLT) 2015. For an expected loss function of a deep nonlinear neural network, ...
An Analysis of the Search Spaces for Generate and Validate Patch Generation Systems
(2016-02-18)
We present the first systematic analysis of the characteristics of patch search spaces for automatic patch generation systems. We analyze the search spaces of two current state-of- the-art systems, SPR and Prophet, with ...
Delphi: A Software Controller for Mobile Network Selection
(2016-02-25)
This paper presents Delphi, a mobile software controller that helps applications select the best network among available choices for their data transfers. Delphi optimizes a specified objective such as transfer completion ...
Outlier Detection in Heterogeneous Datasets using Automatic Tuple Expansion
(2016-02-08)
Rapidly developing areas of information technology are generating massive amounts of data. Human errors, sensor failures, and other unforeseen circumstances unfortunately tend to undermine the quality and consistency of ...
Initial report on Object Spreadsheets
(2016-01-12)
There is a growing demand for data-driven web applications that help automate organizational and business processes of low to medium complexity by letting users view and update structured data in controlled ways. We present ...
